Irrigation, the process of applying controlled amounts of water to plants, can also create various problems for the environment. It can lead to the depletion of underground layers of water that are crucial for the environment.


What is deforestation caused by?

Farmers often cause deforestation by clearing land for their crops. Most of the deforestation happens because of slash-and-burn farming.


How does the Earth’s ability to absorb light and heat affect biodiversity?

What this means is that the ability of the Earth to either absorb or reflect light and heat can change drastically. This leads to radiative forcing, which is the difference between the absorbed sunlight and the reflected energy.

What happens when we clear land for agriculture?

Forests, grasslands, and other ecosystems are converted for farmland. When we clear land for agriculture, we often lose some soil.


What is the result of eutrophication?

The result may be eutrophication, an excessive amount of nutrients in a body of water resulting in a substantial growth of plants, such as algae, and a lack of oxygen in the water because of this increase in plants. There is a finite amount of land on the planet, and agricultural practices take up a lot of land.


Where do fertilizers end up?

Fertilizers, while a nutrient for some plants, end up in streams and lakes in amounts higher than would occur naturally.


Does soil degrade over time?

Thus, the soil degrades over time. If we’re in areas with heavy rainfall, replacing forests with cropland often results in an increase in flooding. Another problem has to do with the amount of water some crops require. Agriculture is the industry with the largest water consumption.


How has agriculture increased?

Agricultural methods have intensified continuously ever since the Industrial Revolution, and even more so since the “green revolution” in the middle decades of the 20 th century. At each stage, innovations in farming techniques brought about huge increases in crop yields by area of arable land. This tremendous rise in food production has sustained a global population that has quadrupled in size over the span of one century. As the human population continues to grow, so too has the amount of space dedicated to feeding it. According to World Bank figures, in 2016, more than 700 million hectares (1.7 billion acres) were devoted to growing corn, wheat, rice, and other staple cereal grains—nearly half of all cultivated land on the planet.


What is the impact of livestock on the environment?

In addition, overgrazing is a major problem regarding environmental sustainability. In some places, stretches of forage land are consumed so extensively that grasses are unable to regenerate.


What causes algae blooms in China?

Nutrient pollution is a causal factor in toxic algae blooms affecting lakes in China, the United States, and elsewhere. As excessive amounts of organic matter decompose in aquatic environments, they can bring about oxygen depletion and create “dead zones” within bodies of water, where nothing can survive.


What are the causes of the pollution of the soil?

The excess levels of nitrogen and phosphorus have caused the once-beneficial nutrients to become pollutants. Roughly half the nitrogen in synthetic fertilizers escapes from the fields where it is applied, finding its way into the soil, air, water, and rainfall.


How does nitrogen affect the environment?

While these chemicals have helped double the rate of food production, they have also helped bring about a gigantic increase, perhaps as high as 600 percent, of reactive nitrogen levels throughout the environment. The excess levels of nitrogen and phosphorus have caused the once-beneficial nutrients to become pollutants. Roughly half the nitrogen in synthetic fertilizers escapes from the fields where it is applied, finding its way into the soil, air, water, and rainfall. After soil bacteria convert fertilizer nitrogen into nitrates, rainstorms or irrigation systems carry these toxins into groundwater and river systems. Accumulated nitrogen and phosphorus harm terrestrial and aquatic ecosystems by loading them with too many nutrients, a process known as eutrophication. Nutrient pollution is a causal factor in toxic algae blooms affecting lakes in China, the United States, and elsewhere. As excessive amounts of organic matter decompose in aquatic environments, they can bring about oxygen depletion and create “dead zones” within bodies of water, where nothing can survive. Parts of the Gulf of Mexico are regularly afflicted in this manner. Nitrogen accumulation in water and on land threatens biodiversity and the health of native plant species and natural habitats. In addition, fertilizer application in soil leads to the formation and release of nitrous oxide, one of the most harmful greenhouse gases.

Why is agriculture important?

For many economies, especially those of developing countries, agriculture can be an important engine—driving force—of economic growth . Approximately three‐quarters of the world’s agricultural value added is generated in developing countries where agriculture constitutes the backbone of the economy. But not only in the developing countries but also in the developed countries agriculture has always been the precursor to the rise of industry and services [ 8 ].


How does land use affect biodiversity?

Land use, specifically in agriculture, has great impact on biodiversity. Another aspect contributing to biodiversity decline is that humans today depend for survival on tiny fraction of wild species that has been domesticated. Yet only 14 of 148 species weighing 45 kg or more were actually domesticated. Similarly, worldwide there are about 200,000 wild species of higher plants, of which only about 100 yielded valuable domesticates [ 53 ].


How did cropland expansion affect agriculture?

The mix of cropland expansion and agricultural intensification has varied geographically. Tropical Asia increased its food production mainly by increasing fertilizer use and irrigation. Most of Africa and Latin America increased their food production through both agricultural intensification and extensification. In western Africa cropland expansion was accompanied by a decrease in fertilizer use and a slight increase in irrigation [ 18 ]. Agriculture is the single largest user of freshwater resources, using a global average of 70% of all surface water supplies.


What are the driving forces of agriculture?

Agricultural ecosystems are interlinked with rural areas where more than 3 billion people live, almost half of the world’s population. Roughly 2.5 billion of these rural people derive their livelihoods from agriculture. Thus, population and land‐use trends are considered to be the main driving forces for agriculture. Besides these driving forces, EEA [ 7] further distinguished the so‐called external and internal driving forces originating from market trends, technological and social changes, as well as the policy framework.


How does land use affect climate?

Land‐cover changes are responsible for surface and vegetation modifications what reflects in surface albedo and thus surface‐atmosphere energy exchanges , which have an impact on regional climate. Terrestrial ecosystems are important sources and sinks of carbon and thus land‐use changes reflect also in the carbon cycle. The important contribution of local evapotranspiration to the water cycle—that is precipitation recycling—as a function of land cover highlighted yet another considerable impact of land‐use/cover change on climate, at a local to regional scale [ 50 ].


How has agriculture changed over the past 50 years?

Agriculture in the last century has evolved from self‐sufficiency to surplus in some parts of the world. Thus, transformation was connected with intensification and specialization of production as main trends in European or North American agriculture accompanied by negative impact on the environment. Agricultural intensification is defined as higher levels of inputs and increased output of cultivated or reared products per unit area and time [ 27 ]. Over the past 50 years, agricultural production has grown between 2.5 and 3 times, thanks to significant increase in the yield of major crops [ 14 ]. Changing land‐use practices have enabled world grain harvests to double from 1.2 to 2.5 billion tonnes per year between 1970 and 2010. Globally, since 1970, there has been a 1.4‐fold increase in the numbers of cattle and buffalo, sheep and goats, and increases of 1.6‐ and 3.7‐fold for pigs and poultry, respectively [ 28 ].


How does human activity affect land use?

Land cover and land‐use patterns on Earth reflect the interaction of human activities and the natural environment [ 1 ]. Human population growth together with competitive land use causes land scarcity, conversion of wild lands to agriculture and other uses. As we can see, the anthropogenic factor has an important impact on land use and land cover changes. Given this human influence, especially during the past 100 years, the recent period has been called the Anthropocene Age [ 2 ]. Human influence on the land and other natural resources is accelerating because of rapid population growth and increasing food requirements. The increasing agricultural intensity generates pressure not only on land resources but also across the whole environment. These factors make agriculture a top‐priority sector for both economic and environmental policy.
